Post-Tropical Cyclone Genevieve Discussion Number 22
NWS National Hurricane Center Miami FL EP122020
200 PM PDT Fri Aug 21 2020
Cool waters and less favorable thermodynamic conditions have
continued to take a toll on Genevieve. The system has not had any
deep convection for more than 12 hours, and it is unlikely that any
organized deep convection will return. As a result, Genevieve has
become a post-tropical cyclone and this will be the final NHC
advisory on this system. The initial wind speed is set at 35 kt,
which is in agreement with recent scatterometer data. The
post-tropical cyclone should continue to gradually weaken over
cooler water during the next couple of days, and the global model
guidance indicates that the circulation will become an open trough
within 72 hours.
The cyclone continues to move northwestward at about 10 kt. A
northwestward motion is forecast to continue over the next couple of
days, but the forward speed of the system is expected to slow as it
becomes increasing shallow and is steered by the weaker low-level
flow. The track guidance remains tightly clustered and the new
foreast is an extension of the previous advisory.
This is the final NHC advisory on Genevieve. Additional information
on the post-tropical cyclone can be found in High Seas Forecasts
issued by the National Weather Service, under AWIPS header
NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at
